I have Ubuntu 14.04 LTS as Dual-Boot with Windows 7 and everything worked superb. Then as I booted my PC GNU Grub rescue popped up and told me, that it couldn't find my SSD.
But as I booted into the Boot selecter of the BIOS it worked great and both OS's would boot without porblems. But it annoys me, that I have to boot into the Boot Selector everytime and I don't want to delete Ubuntu.
Thanks for your answers :)
